 rufo-fuscous. Head short, transverse, not produced ; eyes tolerably 

 large, situated at the base of the head, extending laterally as far as 

 the anterior angles of the thorax ; above the labrum is a transverse 

 plane depression ; between the eyes is a very minute longitudinal 

 fovea, well-defined and thread-like, which reaches at its upper ex- 

 tremity a broad and shallow transverse depression extending between 

 the inner and upper margins of the eyes : the surface (when viewed 

 under a high power) is finely granulated and sparingly pubescent ; 

 in colour rufo-fuscous, at the base more darkly fuscous. Tliorax 

 transverse (nearly quadrate) ; the anterior angles are depressed ; the 

 sides marginate, and in outline subsinuatc ; the anterior margin is
